High-performance thermal insulation fixing anchors engineered for fastening rigid insulation boards, EPS, XPS, rockwool, and fiberglass batts to masonry and concrete substructures. Designed with a broad perforated plastic washer head that firmly clamps insulation material without crushing or pulling through the surface, while providing an ideal key for plaster and basecoat rendering. Fitted with an impact-resistant drive pin (expansion nail) that locks securely into pre-drilled masonry, minimizing thermal bridging and delivering superior wind-load pull-out resistance.
